Digital Image Processing Topics

Learn more about Image Processing here, we have listed latest list of digital image processing topics for thesis and research. Digital image processing furnishes the well-established platform for employing complex approaches for processing digital images to enhance image interpretation and representation. And, it can even perform operations that are hard to work with analog processing methods. Hence, it is widely used in many research fields that deal with image processing areas.

What are the Types of Image Processing?

In general, there are two major categories of techniques for image processing. And they are analog image processing and digital image processing. Analog image processing takes place in 2D analog signals, which are used for photographic films and printouts. Here, image analysts use various chemical components to develop and visualize the image. But in the case of digital image processing, it is processed through intelligent algorithms and approaches in the digital computer where the output is also in the digital image.
